H. P. TROENDLY BUCKLE Filed April 22, 1957 Patented May 2, 1939 UNITED STATES BUCKLE Harry P. Troendly, Chicago, 111., assignor to Parva Products Company, Chicago, lilL, a corporation of Delaware Application April 22, 1937, Serial No. 138,319

3 Claims.

This invention relates to a buckle and has special reference to a buckle adapted to be adjustably associated with straps, bands, and the like, for the support of garments or other objects on 5 the person.

More particularly, this invention relates to a slide buckle formed preferably of a single piece of sheet metal constituting a frame having spaced sides and having a third side connecting the spaced sides with a depending portion turned back upon itself in a spaced relation to form a hook, the hook being reenforced by displacing or upsetting a portion of the material thereof out of its normal plane and having a contracted neck portion adjacent the open end of the hook to prevent disengagement of a member to be supported thereby.

It is contemplated by the present invention to adopt this construction for use with straps,

bands, belts and the like for the support of various types of objects particularly on the person. However, in the drawing and in the following description, the buckle will be shown and described in connection with the shoulder strap and bib of an overall, the strap being threaded through the frame of the buckle in a desired manner. It is readily apparent, of course, that various other uses could be mentioned in connection with buckles and fasteners generally of the type adapted to be adjustably associated with straps, and that this invention, therefore, is not to be limited to the specific use herein described and illustrated.

In a buckle of the above noted type, it is highly desirable to provide for the utmost simplicity and ease of operation in connecting and disconnecting the supported object from the supporting element. In the present invention the arrangement of the hook is such as to co-cperate with a ring or other detachable member for accomplishing the above desired result. Further, the construction and arrangement of the elements of the buckle are such as to minimize the weight and expense from a standpoint of material used as well as for economy in storing and shipping.

The present buckle is preferably formed of a comparatively thin material to be manufactured in a single stamping operation. By reason of the use of a comparatively thin ntaterial in a single piece, the buckle is embossed for obtaining a maximum strength and the embossing is peculiarly adapted to provide a desired hook for detachably receiving the article to be supported.

One of the objects of this invention is to pro- 65 vide a buckle of the character indicated above in which a reinforced hook portion is formed on a buckle of maximum strength and of a minimum weight material.

Another object of this invention is to provide a buckle of the type above noted which is formed 5 of a single sheet of metal to be comparatively inexpensive to manufacture, simple and efficient in operation and economical in shipping and storing.

Other objects and advantages will hereinafter be more particularly pointed out, and for a more complete understanding of the characteristic features of this invention, reference'may now be had to the following description when taken together with the accompanying drawing, in which latter:

Figure 1 is a perspective view of a buckle incorporating the features of this invention;

Figure 2 is an enlarged fragmental vertical sectional View taken on the line 22 of Figure 1;

Figure 3 is an enlarged plan sectional view taken on the line 3--3 of Figure 1;

Figure 4 is an enlarged perspective view of a fragmentary portion of the buckle showing an initial step in the formation of the hook portion; and

Figure 5 is a view similar to Figure 4 showing a further step in the formation of the hook member. 30

Referring now more particularly to the drawing, the buckle of this invention preferably comprises a frame having side bars l0 and II connected by cross bars I2, l3, l4 and I5. The cross bars and side bars are of channel-shape to form an embossed frame, the embossing giving the buckle frame the strength of a flat frame of substantially greater thickness. The lower cross bar I5 is formed with a depending portion l6 which is turned back upon itself in a spaced relation to form a hook, the hook being preferably formed integrally with the lower cross bar [5 of the frame.

Referring now more particularly to Figure 4 of the drawing, the hook portion is initially formed in the same manner as the side bars and cross bars; that is, of channel or embossed shape by providing a flange ll about a depending portion E3, the flanges extending in the same direction as the embossing of the side bars and cross bars. Referring now to Figure 5 of the drawing, the flange H is shown as being flattened against the depending portion l8 and the latter is formed into a hook as indicated by the dotted lines in Figure 5 and as indicated in full lines in Figures 1 and 2.

In order to provide for a snap engagement with the hook portion of a ring 19 or other attaching means secured to the bib of an overall or the like, a detent 20 is preferably formed in the material of the depending portion l8, the detent providing a contracted neck portion adjacent the open end of the hook. The ring l9 forces the detent 20 outwardly in passing into the hook portion and is detachably engaged therein as the detent 20 springs back into an initial position. Of course, the detent 2B is merely one manner of providing a restricted opening adjacent the upper end to prevent accidental displacement of the supported article.

While but a single embodiment of this invention is herein shown and described, it is to be understood that various modifications thereof may be apparent to those skilled in the art without departing from the spirit and scope of this invention and, therefore, the same is only to be limited by the scope of the prior art and the appended claims.

I claim:

In a loop slide buckle comprising an embossed frame having spaced sides and having a third side connecting said spaced sides formed with a depending portion turned back upon itself in a spaced relation to form a hook, said hook being reenforced by having the embossing thereof flattened against the main body portion and having a contracted neck portion adjacent the open end of the hook to prevent accidental displacement of a member to be supported thereby.

2. In a loop slide buckle comprising a frame having spaced side bars connected by spaced cross bars, one of said cross bars being formed with an integrally formed depending portion looped back upon itself in a spaced relation to form a hook-shaped member for the support of garments or the like, at least the looped portion of the hook-shaped member having the outer edges thereof rolled over in a direction toward each other.

3. In a loop slide buckle comprising a frame having spaced embossed side bars connected by spaced embossed cross bars, one of said cross bars being formed with an integrally formed depending portion looped back upon itself in a spaced relation to form a hook-shaped member for the support of garments or the like, at least the looped portion of the hook-shaped member having the outer edges thereof rolled over in a direction toward each other, and means on said hook-shaped member for preventing the accidental displacement of a member to be supported thereby.
